low-e insulated tempered glass for building and decoration

Low-e glass is a commercially available, energy efficient glass that has a special coating that helps to control heat transfer to the building’s interior. Although these windows cost more than typical windows, they reduce the loss of energy as much as 30-50%. Low-e glass provides insulation from both heat and cold.

Low-e glass is coated with an ultra-thin layer of metal. This metallic layer not only allows seeing through, but also provides the actual insulation.

The "E" in low-e stands for emissivity. Emissivity means the power of a surface to reflect heat by radiation. Or you can say that it means to give off or to throw off heat. Emissivity is the value of a material that is calculated as the ratio of heat emitted by that surface as compared to a black body (a thermally black surface). It is measured on a scale from 0 to 1. While a black body would have an emissivity value of 1, a perfect thermal reflector would have an emissivity value of 0.

Low-e glass is called this because it has a low rate of emission. If there is a heat source inside the house and you have low-e glass there, the heat will be bounced back. In winter, much of the heat given off by the appliances in your home will stay there if you have low-e glass.

Similarly, having low-e glass is wonderful for summers, too, as it does not allows solar heat to transmit into your home. This makes it beneficial to use low-e glass to reduce solar heating.

However, all low-e glasses are not equally efficient. They are differentiated on the basis of R-value. The R-value is the measure of resistance to heat loss. A material with higher R-value has better insulating properties.
